In America, conkers are often called "buckeyes," which is the North American name for horse chestnuts. This name comes from the resemblance of the seeds to the eye of a buck (male deer). The term "buckeyes" is commonly used in the United States, especially in places like Ohio, which is nicknamed the Buckeye State due to the abundance of these trees.

Background

• The game involving conkers is also known as "conkers" in the USA but tends to be less widespread compared to Britain.
• The seeds called conkers in Britain are usually smaller in the US, possibly due to different species of horse chestnut.
• The North American "buckeye" is closely related to the horse chestnut and shares similar characteristics.

Thus, conkers in America are called buckeyes.
